Intraoperatively, the right nasal cavity was examined and a large ulcerated lesion was noted on the anterosuperior septum. |
The preferred location for the ostium created by DCR is through the lacrimal bone in the anterosuperior part of the lateral nasal wall. |
There was also an avulsion fracture of the anterosuperior acetabulum and a severely comminuted fracture of the right femoral neck with cephalad displacement. |
The surgeon uses unipolar or bipolar electrosurgery to place a midline anterosuperior mark on the inner perichondrium. |
